3 Claims.

This invention relates to paper making apparatus and is directed moreparticularly to improvements in slice construction adapted for use inconnection with the Fourdrinier wire of a paper machine.

The principal objects of the invention are directed to the provision ofslice apparatus which is constructed and arranged in a novel manner soas to facilitate economy in manufacture and assembly and which may bereadily and easily associated with a paper machine.

As a special feature of the invention the slice construction isadjustable back and forth so that stance another slice, head box or thelike.

According to another novel feature of the ini the construction is suchas to provide j so that the free edge of the slice plate may be adjustedrelative to the Fourdrinier wire and the adjustment maintained.

To the above cited and other ends and with the foregoing and variousother novel features and advantages and other objects of my invention aswill become more readily apparent as the description proceeds, myinvention consists in certain novel features of construction and in thecombination and arrangement of parts as will be hereinafter moreparticularly pointed out in the claims hereunto annexed and more fullyde- M scribed and referred to in connection with the accompanyingdrawings wherein:

Fig. 1 is a side elevational View of the bracket and slide arrangementof the slice construction of the invention.

Fig. 2 is a sectional elevational view on the line 2-2 of Fig. 1 andFig. 3 is a sectional elevational view on the line 3-3 of Fig. 2.

Referring now to the drawing more in detail, the invention will be fullydescribed.

Elongated side plates are represented by 2 which may extend along thepaper machine at opposite sides of the Fourdrinier wire.

Elongated plates t are secured to outer sides of plates 2 by anysuitable means and are formed so as to cooperate with said plates 2 toprovide elongated T-slots as shown, which are disposed horizontally.Brackets t are provided which are slidable along the members 4. Boltshaving heads 8 in the T-slots extend through the brackets t and havenuts it on outer ends thereof for securing the brackets in adjustedpositions.

The brackets t, as will appeansupport the slice structure and they maybe secured to the side plates to locate the slice as may be desiredrelative to other units of the machine.

Boxes iii are adjustable up and down in the brackets t and adjustingscrews M in threaded engagement with said brackets engage lower sidesthereof to adjust the boxes up and down. Hand wheels it are fixed on thesaid screws l4 and locking members 18 are provided on said screws.

The boxes l'2 are split, as shown, and receive opposite end portions ofa tubular support 20. Screws 22 in engagement with upper portions of theblock l2 are provided for clamping the support 2c in the boxes and isprovided with a manually engageable member 24.

Slice brackets 26 are provided on the support which are split, as shown.Screws 28 in engagement with said brackets are provided for clamping thebrackets to the support and have hand wheels 30 for turning the same.

Keys such as 32 are associated with the support 20 and brackets 26, asshown. The brackets 26 may be moved along the support to adjustedpositions and secured therein by the screws 28. A keyway 3 5 for thekeys 32 may if de sired extend along the support 2t.

Relatively diverging arms 36 and 38 extend from the brackets 26. Anelongated reinforcing member lit and a slice plate 42 are secured to thebracket arms 36 by bolts 44 or the like. The slice plate 42 will beformed from relatively thin sheet metal and the member it will berelatively more rigid to reinforce the upper edge of said plate 42.

Blocks it are secured to the lower marginal edge portion of the plate 42and are arranged to provide slots therebetween, as shown. Adjustingscrews 48 in the arms 38 of the brackets, have heads 50 disposed in saidslots and hand wheels 52 are in threaded engagement with upper ends ofsaid screws 68. Lock nuts 55 are provided on the screws 48 and aredisposed in slots 55 provided in the outer ends of arms 38.

As will be seen the lower longitudinal edge of the plate 42 may beadjusted relative to the Fourdrinier wire by means of the screws at toobtain the desired functioning of the slice. The adjustment is securedby the lock nuts.

The longitudinal support may be oscillated in one direction or the otherand secured in ad-- justed positions by the screw 22 whereby the angleof the plate relative to the Fourdrinier wire may be as desired.

' The brackets 6 and slice apparatus may be moved back and forth tolocate the slice relative to other units of a paper machine as may bedesired.

The invention may be embodied in other specific forms without departingfrom the essential characteristics thereof. Hence, the presentembodiments are therefore to be considered in all respects merely asbeing illustrative and not as being restrictive, the scope of theinvention being indicated by the appended claims rather than by theforegoing description, and all modifications and variations as fallwithin the meaning and purview of equivalency of the appended claims aretherefore intended to be embraced therein.
